adding debugedit package. (#22458)

This package used to be a part of rpm, but now is being developed separately.
It will supposedly be moved to a sourceware branch (it is maintained by
redhat) but I do not know if this will happen soon. We need it in order
to change locations in binaries that are built in /tmp and then moved
elsewhere. I will ping @woodard who might be able to give us an estimate
if we should include this development repository or wait for it to be
moved elsewhere. Once this is merged, we will want to use the bootstrap
approach to install and use the library from spack.
